chemical spray pyrolysis deposition of zinc sulphide thin films using Ethylenediaminetetraacetic Acid disodium salt complexant
Journal of Solid State Electrochemistry, 2017Co-Authors: P O Offo, Assumpta C Nwanya, A D Omah, C C Danielmkpume, M Maaza, A Okorie, Fabia I EzemaAbstract:Zinc sulphide thin films were deposited by chemical spray pyrolysis technique. The films were deposited at substrate temperatures of 300, 350 and 400 °C using 0.1 M zinc chloride, 0.1 M thiourea and 0.01 M Ethylenediaminetetraacetic Acid disodium salt (EDTA). The films have moderate transmittance between 56.00 and 77.73% over visible range, and the band gap energy varies between 3.87 and 4.12 eV. The films have high values of refractive index in the range 1.67 to 2.71 at 550 nm. The X-ray diffraction analysis of the films shows the presence of hexagonal and cubic structures. The crystallite size ranges between 6.122 and 43.023 nm. The surface morphology is flower-like, sheet-like and island-shaped nanoclusters. Raman spectroscopy reveals the presence of first-order, second-order and third-order Raman phonons. The Fourier transform infrared spectra show the presence of chemical bonds in the thin films while photoluminescence shows near band edge emission. The contact angle indicated hydrophilic nature of the deposited ZnS thin films.

synthesis of lead zirconate titanate cobalt ferrite magnetoelectric particulate composites via an Ethylenediaminetetraacetic Acid citrate gel process
Scripta Materialia, 2007Co-Authors: Luqian Weng, Yadong Fu, Shenhua Song, Jiaoning Tang, Junqin LiAbstract:Magnetoelectric particulate composites composed of Pb ( Zr 0.48 Ti 0.52 ) O 3 (PZT) and CoFe 2 O 4 (CFO) (molar ratio: PZT / CFO = 1:1) are prepared via an Ethylenediaminetetraacetic Acid (EDTA)–citrate gel process. In the composite sample sintered at 1080 °C, crystalline CFO particles 1–2 μm in size are uniformly distributed in the PZT matrix, which has a grain size of 0.3–0.5 μm. This microstructure leads to a high electrical resistivity (∼ 1.8 × 10 11 Ω cm ) , which is a significant improvement on previous studies.
